Abstract

Three vegetables of thistle, patchouli and fennel in same growing condition were collected, pretreated by microwave digestion and determined for contents of K, Ca, Mg and Pb by atomic absorption spectrometry method. The results showed that the stems and leaves of three vegetables contained abundant K, Ca and Mg. Moreover, a certain amount of Pb was also detected in whole plants of three vegetables. The enrichment characteristics of four elements across different parts of three vegetables were specific. In that, the element K was preferentially accumulated in stem of thistle and patchouli and leaf of fennel. By contrast, the Ca and Mg were preferentially accumulated in leaves of thistle, patchouli and fennel.In daily life, people can choose vegetables according to their different requirements based on the different trace elements and mineral elements in different vegetables to keep balance of trace elements in body and keep health.
